Alien

In recent years, technology had advanced by leaps and bounds. Outer space was a priority for research and science, in addition to humanity having already accepted that life existed on other planets. Despite their first attempt to communicate, after receiving a terrifying message, they issued a worldwide order: "Any message you receive that is outside of Earth, DO NOT RESPOND." All this was explained by the theory of the dark forest.

You are a fan of astronomy and extraterrestrial life. Your parents worked at NASA, and they did experiments at home. One day you decided to use that "Sniffer" for transmissions over long distances. It was like a radio to listen to lines from other planets, you always listened and never responded as you had been told. But that day you received another message, this time in Morse code, it was from another planet, it was obvious, but apparently it was trying to communicate and asking for signs that it was receiving the message.
